Description

  The present invention relates to a railway vehicle structure in which each structure constituted by an extruded shape member in which two facing face plates are connected by a rib and a frame are assembled by mechanical fastening means such as rivets or bolts.

  A railway vehicle structure is generally composed of a roof structure that constitutes the upper surface of the vehicle body, a side structure that constitutes the side surface, a base frame that constitutes the lower surface, and a wife structure that constitutes the longitudinal end surface of the structure. In recent years, roof structures, side structures, etc. have been constructed with extruded shapes made of aluminum alloy consisting of two face plates and a plurality of connecting ribs connecting the face plates, with the main purpose of reducing weight and improving manufacturability. The method of assembling a railway vehicle structure is becoming widespread.

  In general, first, a predetermined number of extruded shapes extruded into a predetermined shape are disposed on the upper surface of the gantry along the direction of extrusion, and then the bonded surfaces of the extruded shapes are joined together. A roof structure, side structure, underframe, etc. are manufactured by friction stir welding or welding along the line. Next, the wife structure is erected at both ends in the longitudinal direction of the underframe, and the side structure is erected at both ends in the width direction of the underframe so that the lower end of the wife structure and the side structure and the underframe The connecting portion and the connecting portion in the vertical direction between the wife structure and the side structure are connected by welding or the like. Finally, the roof structure is placed on the upper end of the wife structure and the side structure, and the connection portion between the wife structure and the side structure and the roof structure is connected by welding or the like, so that a six-sided railway vehicle structure is manufactured. . The structure of the railway vehicle structure manufactured in this way is shown in Patent Document 1, for example.

  Conventionally, after fitting equipment such as chairs, hanging leather, and interior parts into a railway car structure that is configured in a hexahedron, these equipment are attached to predetermined positions on the side structure, roof structure, and underframe. It was. The conventional installation work of the equipment includes the protective material installation work to protect the equipment, the import of the equipment into the inside of the railway vehicle structure, the removal work of the protective material, the installation work of the equipment to the railway vehicle structure, The work consisted of carrying out protective material, etc., and there was a tendency for the work man-hours to increase.

  Therefore, in order to reduce work man-hours and increase productivity, a method has been developed to manufacture hexahedral railcar structures after attaching outfittings to side structures, roof structures, underframes, etc. in advance by outwork. . In this method, each structure and underframe to which the equipment is attached in advance are connected, so the connection between the underframe and the side structure, the connection between the side structure and the roof structure, It is difficult to use welded joints that are susceptible to large amounts of heat that can be affected. Therefore, mechanical fastening means such as bolts and rivets without heat input are applied to these connecting portions.

  FIG. 11 is a cross-sectional view (C portion in FIG. 2) of a conventional connecting portion between the side structure 20 and the roof structure 40 by mechanical fastening means. Similarly, FIG. 12 shows the frame 10 and the side structure 20. It is the conventional connection part (D section of FIG. 2). Each structure such as the underframe 10, the side structure 20, and the roof structure 40 is fastened by mechanical fastening means such as a rivet 100 a or a bolt to constitute the railway vehicle structure 1. When the connecting portion between the underframe 10 and the side structure 20 or the connecting portion between the side structure 20 and the roof structure 40 is fastened, the top of the rivet 100a comes from the surface of one surface of the extruded shape member constituting each structure. Protruding. For this reason, in order to conceal the top of the rivet and configure a railway vehicle with high design, a seal 110 for preventing water from entering the top of the rivet and its surroundings is applied and then discretely fastened. A plan to cover the entire top of the rivet with a cover 200 or the like has been studied. However, not only the work man-hour is increased in order to construct the cover 200 that covers the top of the rivet, but in particular, the vehicle is provided by the cover 200 having a thickness B at the connection portion between the side structure 20 and the roof structure 30 shown in FIG. Since the outer edge of the limit 500 is defined, there is a problem that the cabin space is reduced by a volume corresponding to the gap between the cover 200 and the outer surface of the railway vehicle structure 1.

Hereinafter, an example of a railway vehicle structure according to the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view schematically showing an example of a railway vehicle structure. The railcar structure 1 shown in FIG. 1 has side structures 20 and 20 (only one is shown) standing at both ends in the width direction of the underframe 10 and a wife standing at both ends in the longitudinal direction of the underframe 10. The structure 30, 30 (only one is shown), the side structure 20, 20, and the roof structure 40 mounted on the upper end portion of the wife structure 30, 30, and both ends in the longitudinal direction are support portions (carts). 400,400.

  FIG. 2 is a longitudinal half of the longitudinal vertical cross section (central portion) of the railway vehicle structure 1 shown in FIG. The railway vehicle structure 1 connects the frame 10 and the side structure 20 erected on the frame 10 (D portion), and the roof structure 40 placed on the side structure 20 and the upper end of the side structure 20. Are connected (C section). The side structure 20, the roof structure 40, and the underframe 10 are formed by arranging a plurality of extruded shapes in which two facing face plates are connected by a plurality of ribs along the extrusion direction, and the width direction of the extruded shape material (in the extrusion direction). After the end portions in the crossing direction) are butted together, they are assembled into a flat plate having a predetermined width and length by friction stir welding or welding. Each structure assembled in a flat plate shape is provided with an opening at a predetermined position. In the case of the side structure 20, the opening is a side opening 60 or a window 65 (see FIG. 1) provided with a side sliding door that is used for passengers getting on and off. These are an opening for sending conditioned air from the air conditioner to be placed into the inside of the railway vehicle structure 1 and an opening for returning the recirculated air from the vehicle to the air conditioner.

  In the railway vehicle structure 1, the frame 10 and the side structure 20 are the inner and outer face plates of the extruded shape member positioned at the end of the frame 10 in the width direction, and the height direction of the side structure 20. In the connection part D where the inner side and the outer side face plates of the extruded shape member positioned at the lower end of the vehicle are overlapped, they are dispersed along the longitudinal direction of the railway vehicle body 1 by mechanical fastening means such as bolts and rivets. Connected. Similarly, the side structure 20 and the roof structure 40 are formed on the inner and outer face plates of the extruded shape member positioned at the upper end of the side structure 20 in the height direction, and on the end of the roof structure 40 in the width direction. In the connection portion C where the inner side and the outer side face plates of the extruded profile member positioned are overlapped, they are discretely connected by rivets (mechanical fastening means) along the longitudinal direction of the railway vehicle structure 1.

  FIG. 3 is a cross-sectional view crossing the longitudinal direction (extrusion direction perpendicular to the paper surface) of the extruded shape member 41 forming the roof structure 40. A connection portion C between the roof structure 40 and the side structure 20 is configured using an end portion 50 formed to extend in the width direction 250 intersecting the extrusion direction of the extruded shape member 41.

  The extruded shape member 41 is integrally molded in a form in which the first face plate 42 and the second face plate 44 are joined by the rib 46 and the end rib 48. The end portion of the first face plate 42 protrudes in the width direction 250 side from the end portion of the second face plate 44, and the end rib 48 is the end portion of the second face plate 44 and the center portion in the width direction of the first face plate 42. It joins the close part. The thickness of the end portion 50 of the first face plate 42 is reduced by the thickness (t1) so that the thickness of the top portion of the rivet described later does not protrude from the surface of the first face plate. The end portion 52 of the second face plate 44 is substantially the same as the thickness of the first face plate of the side structure 20 so that when the extruded shape members are connected, the first face plate of the mating extruded shape member can be locked. A step is provided in the thickness direction of the extruded shape member 41 by the thickness (t2).

  4 is a cross-sectional view of the connecting portion C between the end portion in the width direction of the roof structure 40 and the upper end portion of the side structure 20, and FIG. 5 is a plan view of FIG. The first face plate 42 of the extruded shape member constituting the side structure 20 is disposed on the inner side of the railway vehicle structure 1 so that the roof structure 40 can be lowered and placed on the upper end portion of the side structure 20. The second face plate 44 of the extruded shape member of the roof structure 40 is overlapped with the first face plate 42 of the extruded shape member of the side structure 20, and the first face plate 42 of the roof structure 40 is overlapped with the second face plate 44 of the side structure 20. The connection part C of the lap joint is formed. Using the adjustment allowance d formed between the steps of the second face plates 44 of the side structure 20 and the roof structure 40 and the ends of the first face plate 42 of the roof structure 40 and the side structure 20, the roof structure 40 is used. After the fine adjustment of the relative position between the side structure 20 and the side structure 20, the lap joints of the face plates located on the outside of the vehicle are connected by a rivet 100a, and the lap joints of the face plates located on the inside of the car are connected by a rivet 100b.

  For the lap joint of the inner face plate, a one-piece type rivet 100b that does not require a hole for inserting a rivet tool into the outer face plate is used. On the other hand, a rivet 100a of a two-piece type is used for a lap joint of a face plate on the outside of the vehicle, in which a rivet tool is inserted through a hole 105 provided in the face plate on the inside of the vehicle to connect the face plates. In general, since the connection strength of a two-piece type rivet is greater than that of a one-piece type, it is appropriately selected according to the load conditions. In the case of the two-piece type rivet 100a, it is necessary to provide a hole for inserting a rivet tool in the other face plate when constructing a rivet in the connection portion of one face plate. In FIG. 4, a hole 105 for inserting a rivet tool is provided in a face plate inside the vehicle, and the possibility of rainwater or the like entering the vehicle through this hole is reduced, and a two-piece type rivet 100a having a high connection strength is provided on the vehicle exterior. It is an example used for the lap joint of the face plate. After taking measures against intrusion of rainwater or the like, a one-piece type rivet 100b may be used for the connecting portion of the face plate on the outside of the vehicle, like the connecting portion of the face plate on the inside of the vehicle.

  The thickness of the end portion 50 of the first face plate 42 of the roof structure 40 is reduced by the thickness t1 at which the top of the rivet 100a is hidden on the vehicle exterior side, and the roof structure 40 on which the first face plate 42 of the side structure 20 is placed. A step corresponding to the thickness t2 of the first face plate 42 of the side structure 20 is provided at the end of the second face plate 44. Further, the thickness of the end portion 50 of the first face plate 42 of the side structure 20 is reduced inside the vehicle by a thickness t1 at which the top of the rivet 100b is hidden, and the side on which the first face plate 42 of the roof structure 40 is placed. A step having a thickness t2 of the first face plate 42 of the roof structure 40 is provided at the end of the second face plate 44 of the structure 40. By these steps, the face plates (both the vehicle inner side and the vehicle outer side) of the lap joint portion of the side structure 20 and the roof structure 40 are formed on substantially the same surface. For this reason, in particular, since the vehicle outer side surfaces of the side structure 20 and the roof structure 40 including the lap joint portion can be close to the vehicle limit 500, the cabin space can be increased. In addition, since the lap joint portion (both inside and outside the vehicle) is formed on substantially the same surface, the waterproof seal 110 is made small along the rivets 100a and 100b connected discretely (pitch P). It can be constructed with man-hours (see Fig. 5). The seal 110 is provided so as to be flush with the surfaces of the first face plate 42 and the second face plate 44.

  FIG. 6 is another cross-sectional view of the connection portion C between the side structure 20 and the roof structure 40. Changes in the thickness in the width direction (width direction 250 shown in FIG. 3) of the portion where the thickness of the end portion of the first face plate 42 of the extruded shape member forming the side structure 20 or the roof structure 40 is reduced by t1, and the extrusion The change in the plate thickness in the width direction (width direction 250 shown in FIG. 3) (corresponding to t2 in FIG. 3) of the portion where the step is provided at the end of the second face plate 44 of the profile is made gentle. The mass of large equipment such as main transformers and main converters installed under the floor of the railway vehicle structure 1 or the mass of passengers is connected to the connection part (FIG. 2, part C) between the side structure 20 and the roof structure 40. Even when a static load accompanying or a dynamic load due to vibration associated with traveling is applied, the change in the thickness of the first face plate 42 and the second face plate 44 is gentle, so stress concentration is reduced. It is possible to reduce the occurrence.

  FIG. 7 is a cross-sectional view of still another connection portion between the side structure 20 and the roof structure 40, and FIG. 8 is a plan view viewed from the view F (FIG. 7). Since the construction work of the seal 110 includes time required for drying the seal 110, it is desirable to reduce the amount of use of the seal 110 as much as possible. In FIG. 7, in order to reduce the amount of the seal 110 used, the top shapes of the rivets 100 a and 100 b are used instead of reducing the thickness of the end portions of the first face plates 42 of the extruded shape members of the side structure 20 and the roof structure 40. It is an example provided with spot facings. In this example, the depth of the spot facing is such that the top of the rivet is hidden. Accordingly, the seal 110 has a gap between the stepped portion of the side structure 20 and the end of the roof structure 40, a gap between the end of the side structure 20 and the stepped portion of the roof structure 40, and rivets 100a and 100b in the counterbore. It is only necessary to fill the gap around the seal 110, and the amount of use of the seal 110 can be reduced.

  FIG. 9 is a cross-sectional view of still another connection portion between the side structure 20 and the roof structure 40. 7 and 8, the end portion of the second face plate 44 of the extruded shape member forming the side structure 20 or the roof structure 40 in the connection portion which is an example provided with the counterbore according to the top shape of the rivets 100a and 100b. In this example, the change in the plate thickness in the width direction (FIG. 3, 250) of the portion where the step is provided is gently formed, that is, the step is formed gently. Although the amount of use of the seal is slightly increased as compared with the connecting portion shown in FIGS. 7 and 8, even if a static or dynamic load is applied to the railway vehicle assembly 1, the plate of the second face plate 44 is used. Since the change in the cross-sectional area of the thickness is gentle, the occurrence of stress concentration can be reduced.

  In addition, although the Example shown in FIGS. 3-9 mainly described regarding the connection of a roof structure and a side structure, it is applicable also to the connection of a side structure and a base frame.

  FIG. 10 is a cross-sectional view showing an embodiment of the railway vehicle structure 1 according to the present invention, and is a diagram showing a connecting portion (D portion in FIG. 2) between the frame 10 and the side structure 20 used in the railway vehicle structure 1. It is. The extruded shape member arranged at the end of the side structure 20 in the width direction (arrow 250) is configured by connecting the first face plate 42 and the second face plate 44 by a rib 46, a rib 46a, and an end rib 48. . The end 42a in the width direction of the first face plate 42 of the side structure 20 is thinned from the outer surface side toward the vehicle inner side of the railway vehicle structure 1 so that the top of the rivet 100b is hidden. The end portion 44a in the width direction (arrow 260) of the second face plate 44 is extruded to form a substantially horizontal shape so that it can be placed on the end portion in the width direction (arrow 260) of the first face plate 10a of the underframe 10. Is done. In the extruded frame that is configured at the frame 10 and disposed at the end in the width direction of the frame 10, the side beam portion 10B and the floor portion 10A are integrally formed. A step corresponding to the thickness of the second face plate 44a is located at the end of the underframe 10 in the width direction (arrow 260) and where the end 44a of the second face plate 44 of the side structure 20 is placed. It is provided in the direction in which the thickness (arrow 270) of the underframe 10 decreases. By this step, the end portion 44a of the second face plate 44 of the side structure 20 and the vehicle interior surface of the first face plate 10a of the underframe 10 are formed in substantially the same plane.

  The thickness of the end portion 42a in the width direction (arrow 250) of the first face plate 42 of the side structure 20 is reduced on the vehicle exterior side by the thickness t1 of the top of the rivet 100b. The portion of the second face plate 10b of the underframe 10 where the end portion 42a of the first face plate 42 of the side structure 20 is overlapped corresponds to the sum of the thickness of the end portion 42a and the thickness t1 of the top portion of the rivet 100b. A step is provided toward the inner side of the railway vehicle structure 1. Due to this step, when the side structure 20 is connected to the frame 10, the vehicle exterior surfaces of the first face plate 42a of the side structure 20 and the second face plate 10b of the frame 10 are formed in substantially the same plane. With this configuration, the construction of the cover 200 (see FIG. 12) can be omitted from the lap joint portion of the underframe 10 and the side structure 20, and the vehicle outer surface of the lap joint portion is brought close to the vehicle limit 500. As a result, the cabin space can be increased. Since the surface of the lap joint part on the vehicle exterior side of the underframe 10 and the side structure 20 is formed in substantially the same plane, a waterproof seal 110 is provided along the rivets 100b connected discretely (pitch P). Construction can be done with small man-hours. The seal 110 is applied so as to be flush with the outer surface of the first face plate 42 of the side structure 20 and the second face plate 10b of the underframe 10. The lap joint portion on the vehicle inner side of the underframe 10 and the side structure 20 is also connected by a rivet 100b as in the vehicle outer side, and a seal is applied as necessary.
